Book excerpt: Excerpt from Modification of the Method of Mechanical Soil Analysis The mechanical analysis of the soil, as carried out in the Bureau of Soils, has been devised as an expedient method of obtaining a quantitative statement for the classification of soils on a physical basis. There exists a close relationship between the mechanical com position and most of the physical' properties of soils, although the exact nature of the relationship is not. Yet. Satisfactorily known. Many attempts have been made to classify soils upon the basis of some physical property, but to measure any physical property of soils without regard to the mechanical composition would disregard those relations of most importance in the practical management of soils. The physical properties of a soil are dependent upon the structure of the soil as well as upon the mechanical composition. The organic matter present influences both composition and structure. Hence we have a number of dependent variables of whose relations. To one another we yet know very little. But the mechanical composition of any particular soil remains reasonably constant, so that, it has been adopted as a basis for classification until the relationship ex isting between mechanical composition and the physical properties of the soil have become better known. The classification of soils on this basis is of agricultural value, as certain obvious characteristics attach to clays, loams, sands, ietc., as classes. In the mechanical analysis the soil is divided into a number of different grades of particles, whose dimensions lie between definite limits, and the percentage by weight of each of these grades is de termined. In general, the basic methods used in mechanical analysis are separation of different size particles by sifting in the case of the larger particles, and by sedimentation (usually in water) in case of the smaller ones. Various successful modifications have been devised, based on these methods. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.

This book was released on 2017-10-29 with total page 48 pages. Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from The Centrifugal Method of Mechanical Soil Analysis The mechanical analysis of a soil consists (1) in the separation of the soil particles into groups dependent upon the size of the grains, and (2) in the determination of the percentage by weight of the par ticles constituting each group. The limits of these groups are arbi trarily chosen, with reference (a) to the ease in making the separation, and (b) to the importance of the particles of any given size in deter mining the physical characteristics of the soil.

Book excerpt: Excerpt from Methods of Physical and Chemical Soil Analysis That the introduction of the grain-sizes coarser than mm. Can as a rule serve no useful purpose in the chemical analysis of soils in the humid region is strikingly shown in the investigation made by R. H. Loughridge, in 1873 (am. J. Sci., Jan. 1874, p. He found that in the case of a very generalized soil of the Mississippi uplands, solution by strong acid practically ceased beyond the sediment of mm. Hydraulic value, cor responding to a diameter of about mm. Although the general applicability of this particular limit may be fairly questioned, the wide margins between the fractions and renders it pretty certain that within the limit of the former we shall find all that is of any value to plants for their supply of mineral plant food. But for the sake of comparability with analyses made under a different rule, the grain-sizes of to 1 and 1 to 2 mm. Diameter should always be quantitatively determined.

Available in PDF, EPUB and Kindle. Book excerpt: Excerpt from Methods in Soil Analysis: Technical Bulletin Much importance has been attributed in recent years to the analysis of soils for total constituents. The literature covering the -methods for such analysis, while rather exten Sive, is scattered, and in many cases the methods described are not well suited to rapid routine practice. In View of these facts it has been thought that the compilation and publication Of the methods used and in part evolved in the soils laboratory of the West Virginia Agricultural Experiment Station may be of value to others desiring methods which are rapid and at the same time sufficiently accurate to meet the requirements Of most soil investigations. The methods are presented in. Sufficient detail to permit their employment by those who have not had extensive experience in quantitative work.
